' Specification. forming part of Letters Patent No. 39,327, dated July 21, 1863.

'i'oall ughom'it may ctncerrt. I

Be it known that I, ,P. W. REID, of Birmingham, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Preserve-Jar; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,'making a part I of this specification, in which Figure "l is a perspective view of the top or .mouth of my improved jar without the cover. Fig. 2 is a diametrical section through the cover of thejar. Fig. 3 is a top view of the jar with its cover confined in place. Fig. 4 is a sectional view through the mouth andneck of the jar, showingth'e cover seated therein.

-Fig. 5 is a perspective viewot' the cover of last from year to year without renewing or repairing.

'The nature of my invention consists in con 1 structing the mouth of a jar and .the stopper thereof in such amanner as to obtain a screw pressure and fastening, and also a*wedged or tapering bearing, thus enabling me to secure thestopper in the mouth of thejar very firmly,

and at the same time to makea perfectly-tight joint, as will be hereinafter described.

It also consists in constructing-a cylindroconical stopper with an annular recess on its taperingend adapted to receive and to retain in place a rubber gasket or packing-ring,

'1 verse handle or finger plate, which is-depressed or let into a concavity formed in the top of the stopper and used for applying the stopper to the jar, or for removing the same therefrom, as will be hereinafter described. In the accompanying drawings, A repre- "sents the body of the jar, only a part of which is represented. B represents the reduced neck of the jar, and O the enlarged flaring neck of, the same. This flaring mouth consists of two right and left circular and tapering grooves, a a, which terminate at their ends in vertical spaces 1) b and vertical rim, 0. The lower surfaces, (2 d, of the grooves a a incline downward toward the neck ofthe jar and form the rounded and circular shoulder a, which is produced by spreading out the plastic glass in the'mold in the operation of forming the upper portion of the mouth of the jar. The whole jar is made with this form of mouth in a mold suitably adapted to the purpose, and the operation requires no uinisuallabor nor ingenuity in performing the operation.

The cover or stopper for the mouth of this depression, f, in its top, which is divided cenis molded with the stopper, as shown in Fig stopper has two lugs, ii, projecting therefrom, which are situated opposite to each other, and these lugs are formed with rounded ends, adaptv ed to be received by the right'and left tapering grooves a a in the mouth of the jar, as

. shown in Fig. Thedistance across thcstoppers from the extremity of one lug to that of I theother is slightly less thanthe greatest diameter of the mouth of'the jar. The stopper, with its lugs it, may therefore be slipped into the mouth of the jar (by passing the lugs down through the vertical spaces 1) b) and rested upon the shoulder c, and then turned, so that the lugs will pass into the grooves a. a and under the inclined planes thereof. The cylindrical portion h terminates in a tapering or beveled portion of the stopper. The surface of this beveled portion a does not, however, impinge case it would be necessary to grind this surface, and also that against'which it would bear, (the shoulder 42,) which would add greatly to the expense of the jar; but, in lieu around the beveled sides of the stopper, and

band, 1', as shown in Figs. 2, 4, and ,5, and bejar is made of a cylindro-conical shape,with a trally by a fiat handle or finger-piece, that 3. The upper or cylindrical portion, h, of this portion, a, which forms the valve or closing upon the surface of the jar, for if this were the of this objectionable mode, I form a recess, 1),

in this recess I introduce an india-'rubber;'

v confined in its place. The stopper being completed, it is applied to the jar in the following manner: The lugs ii are brought over the spaces b b, and the stopper slipped down into the mouth of the jar. This brings the rubber band or packing rin contact with the'rounded shoulder c on the jar and the lugs z z opposite the widest ends of theirrespcctive grooves a a, so that by giving thestopper a turn the lugs will pass into these grooves and bearagainst the upper'or inclined surfaces thereof and gradually depress the stopper into its seat, which operation compresses the rubber band and spreads itout over and around the shoulder (2 and makes a tight'joint at this point.

To reinove the stopper from the jar it is turned backward; but as the compressed rubber packing r willforcc the lugs hard up against the upper surfaces of the grooves a a, it will be fouud'easier to depress the stopper and to start it in this 'way. As the grooves widen, the hearing will be diminished, untilfinally the lugs will be brought into the spaces 5 b, when the stopper may be easily removed.

The fingerpicee'g isused as a handle, as

shown in Fig. 5, for holding and removing from the jar, and. while this is the case there is no portion of the handle which is liable to 'stantially as herein described.

Having thus described my invention, what I claim as new,-and desire to secure by Letters Patent, is 1 1. The cylindro-conical. stopper, in .combi' nation witlra depressed, handle, 9, and logs it, constructed in such a manner-with reference to the mouth of a jar that I coinbinewith a screwpressure and fastening a wedge-bearing,-'subs'tantially as described.

3. Although I do not claim-,- broadly,ascrewstopper and a rubber packing-ring, I claim constructing the mouth'of a jar with tapering grooves a 01, spaces b b, reduced neck B, 'and rounded or beveled shoulder e, in combination with a cylindro-conical stopper, and a rubber packing-ring, 1', applied to the beveled edge thereof, so asto bear upon the rounded shoulder e andv to form a tight joint, sub- 4. A eylindro conical stopper, 'with lugs i 2', and a depressed handle, g, constructed substantially as and for the purposes herein described.
